SPECIFICATION forming part of I ietters Patent No. 617,898, dated January 17,Y 1899. Application nea my 6, 189s. stanno. 685,282. (No model.)

To all whom it may concern: Be it known that I, HEINRICH FRoBsn, a' subject of the King of Prussia, Emperor of Germany, residing at Bielefeld, in the Kingdem of Prussia, Germany, have invented eertain new and useful Improvements-in or Relating to Lubricators, (for which I have applied for a patent in Germany, filed June 3, 1898; in England, No. 13,118, :filed June 1-1, 1898; in France, led June 11, 1898, and in Belgium, filed 'June 20, 1898,) of lwhich the following is a specification.

This invention relates-to improvements in lubricators, and is especiallyapplieable Vfor use on cycle and similar bearings, and is illustrated in the accompanying drawings in-a form suitable for cycle Wheels and bearings. The device is provided with a doubleclosure for preventing dustfrom penetrating in to the bearings, the inner closure being effected by a plug shutting oil" completely the lubricatorhole from the bearings, while the second additional closure is formed by a cover, both the closures being actuated, as hereinafter described, by a single manipulation.

Figure 1 is a front elevationof the new lubricator. Figs. 2 and 3'are vertical sections ofthe lubricator in the closed and open condition, respectively.v Fig. t is a horizontal section on line A l in Fig. 1.

'lhe lubricator consists, essentially, ofl a body a, preferably made in one piece and provided with a screw-thread b aml is vertically bored out so as to form a lubricant-channel c and horizontally bored out to form a crosschannel (Z, wherein a plug c is located, the latter lhaving a passage f, which when the plug,r is in place in the boring is adapted lo be placed i-n line with tho lubrieaut-channel'c. 'lo the plug is secured, on both sides, on the outside of the bodyaclosure-covcrg. -When the latter is in the horizontal position, (sec Fig. 3,) the lulnieant-channel is open, while when the cover y is in the vertical position, Fig. 2, by the closure of. thc plug, which is cl'icctediby turning the cover, thc lubricantohannel is doubly closod vix., by thcplugf',

. neeted with the cover g,

A spring h maybe arranged in the bodyto i ias'. well as by the cover g-so that dust is effectually prevented from penetrating into the bearings and the lubricant from flowing out.

The double closure of the lubricant-channel is eected, as already mentioned, by a single manipulation, the plug ev being conso as to move with it.

serve 'to retain the plug, and consequently the cover also, in theclosed or open position, and for this purpose the plug may, if desired, have flats formed upon its surface.

The advantage of .this lubricating device consists, in addition to the double closure againstthe entrance of dust and the outowing efoivL-in the easy cleaning of the the lubricating-channel, as after the cover has been opened one may push the cleaninginstrument through the channel up to the bearings.

I claim- 1. The combination ofa body having a channel therein, a plug mounted to turn inthe channel and having a passage capable of registering with the channel, and a cover connected with the plug so as to swing over the body, the plug and cover being joined, s6 that as the plug moves to closed position, the cover moves over the channel in the body.

2. The combination of a body portion having a channel therein, a plug mounted in the body portion to command the channel, anda cover moving over the body portion in unison with the plug to command the channel.

3. lhe combination of a spherical body portion having aehanuel, a plug mounted in the body portion and commanding the channel,

anda curved cover attached to the plugand moving vcr the body portion in lunison with -the pluglo command the channel.

lu witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

HEINRICH FROIHSE.
